  By the way, in the said conventional vacuum cleaner, although handling is easy, in order to collect | recover collection | recovery objects with the dust bag 12, when a collection | recovery volume is small and collect | recovering a lot of collection | recovery objects, There is an inconvenience that a disposal operation for disposing the object to be collected must be frequently performed by removing the clip 12a that closes the bottom of the tray 12 to open the bottom. Moreover, since the dust bag 12 is formed from the material which has air permeability, such as cloth, a liquid cannot be collect | recovered.

  On the other hand, in the suction recovery apparatus described in Patent Document 1, a recovery target object is recovered in a recovery container such as a pail can. Therefore, although a large amount of recovery target object can be recovered by suction, it is considerably large and has a weight. Therefore, it is not suitable for use in a small amount of collected materials, high places, or narrow places compared to handy type vacuum cleaners.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a suction recovery device that can recover a recovery object such as dust in a recovery container such as a pail can by using a vacuum cleaner that recovers the recovery object in a dust bag. That is.

  In order to solve the above problems, in the present invention, a cleaner connection base and a hose connection base having a hose connection hole for connecting a suction hose on the upper surface of a lid that is detachably attached to the opening of the recovery container. A nipple connection hole communicating with the inside of the recovery container is provided in the cleaner connection base, and the suction nozzle connection nipple provided in the hand-type vacuum cleaner is detachable from the nipple connection hole. The vacuum cleaner having the following configuration was adopted.

  One end is an air inlet, the other end is an air outlet, and compressed air ejected from an air injection nozzle provided in the air inlet portion is accelerated to flow out of the other air outlet. A handle is connected to the outer periphery of the air inlet side of the air accelerating diffuser pipe to which a suction force is applied to the air inlet by the action, and the handle is opened and closed by a lever-operated on-off valve. A vacuum cleaner provided with an air supply path for supplying compressed air to an injection nozzle, wherein the nipple is connected to an air inlet of the diffuser pipe, and a breathable dust bag is connected to an air outlet of the diffuser pipe.

  In the suction recovery apparatus having the above-described configuration, when the on-off valve is opened in a state where compressed air is supplied from the air compressor to the air supply path of the vacuum cleaner, the compressed air is injected from the air injection nozzle into the diffuser pipe and accelerated. The air flows out from the air outlet, and the suction force is loaded into the nipple by the ejector action of the compressed air.

  For this reason, by connecting a suction nozzle to the nipple, a collection object such as dust can be sucked by the suction nozzle, and the collection object is transported from the diffuser pipe into the dust bag. Can be recovered.

  In addition, with the lid attached to the recovery container, the inside of the recovery container can be decompressed by connecting the nipple to the nipple connection hole formed in the cleaner connection base, and the hose formed on the hose connection base A suction force can be applied to the connection hole. Therefore, by connecting a suction hose to the hose connection hole, a collection object such as dust can be sucked by the suction hose, and the suctioned collection object can be collected in the collection container.

  In this case, if fine dust is mixed in the collection object collected by suction, the dust flows from the nipple into the diffuser pipe on the flow of suction air acting in the collection container and flows out from the air outlet. there's a possibility that. At this time, since the dust bag is connected to the air outlet, the dust is prevented from being captured by the dust bag and flowing out, and the external environment is not deteriorated.

  Here, a large-diameter hole is provided in the lower part of the nipple connection hole formed in the cleaner connection pedestal, and a filter is incorporated into the large-diameter hole, or the nipple connection hole of the cleaner connection pedestal can be inserted and removed freely. When a filter case having a connection cylinder at one end and a nipple connection hole into which the nipple can be inserted and removed is formed at the other end and the filter is accommodated in the nipple of the cleaner connection base and the vacuum cleaner, Since the dust can be captured by the filter, it is possible to more reliably prevent the dust from leaking to the outside.

  In the use of collecting the object to be collected in the collection container as described above, the inside of the collection container is depressurized, so that the suction nozzle connecting nipple is loaded with a drawing force toward the collection container. For this reason, a stable connection state can be obtained even if a simple connection method by inserting / removing is adopted instead of screw connection as means for making the suction nozzle connecting nipple detachable.

  In the suction recovery apparatus according to the present invention, if the cleaner connecting base and the hose connecting base are made common, the mounting can be facilitated as compared with the case where each base is individually attached to the lid.

  In addition, if holding means for holding the lever for opening / closing the lever-operated on-off valve in the open position is provided, there is no need to hold the lever displaced to the open position by hand, which is effective in reducing hand fatigue. Can be mentioned.

  As the holding means, a U-shaped engagement hook whose both ends are rotatably connected to the outer periphery facing position of the handle, and a pair of operations facing each other in the circumferential direction. It is possible to employ a method in which an engagement ring that has a piece at both ends and is elastically deformable in the radial direction and expands by pinching the pair of operation pieces across the outer periphery of the handle and the lever.

  Here, if a U-shaped handbag is connected to the cleaner connection base so that it can be raised or lowered, or if a fingertip engagement recess is formed on the outer periphery of the cleaner connection base, the lid can be easily attached and detached. Can do.

  As described above, in the present invention, it is possible to use two kinds of use, that is, the use of sucking and collecting the collection object in the dust bag and the use of sucking and collecting the collection object such as dust in a collection container such as a pail can. This is extremely convenient because the usage state can be changed according to the type and amount of the collection object.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the suction recovery device according to the present invention includes a vacuum cleaner A and a recovery container B. Since the vacuum cleaner A is the same as the vacuum cleaner A shown in FIGS. 10 and 11, the same components are denoted by the same reference numerals and description thereof is omitted.

  As shown in FIG. 2, both ends of a U-shaped engagement hook 18 are rotatably connected to the grip portion 13 of the handle 2 in the vacuum cleaner A, and the engagement hook 18 is connected to a lever 17a for opening / closing operation. The lever 17a is held in a state in which the lever 17a is displaced to the open position.

  The holding means for holding the lever 17a in the open position is not limited to this. For example, as shown in FIG. 8, a pair of operation pieces 20 facing each other in the circumferential direction are provided at both ends, and an engagement ring 19 that can be elastically deformed in the radial direction is expanded by picking up the pair of operation pieces 20. May be fitted to the handle 2 and the engagement ring 19 may be expanded to engage the grip portion 13 and the lever 17a.

  As shown in FIG. 1 to FIG. 4, a pail can having a volume of about 20 liters is adopted as the collection container B here. The pail can B includes a can body 30 and a lid 31 that closes an upper opening of the can body 30.

  Here, the pail can B has a type in which the lid 31 is held in a closed state by fastening a fastening band wound around the outer circumference of the lid 31 and the outer circumference of the can body 30, and a plurality of pail cans B attached to the outer circumference of the can body 30. There is a type in which the latch is engaged with the outer peripheral portion of the upper surface of the lid 31 to hold the lid 31 in a closed state, but any type may be adopted.

  A cleaner connecting pedestal 32 is provided on the upper surface of the lid 31 and a hose connecting pedestal 33 is provided around the pedestal 32. It is fixed to the lid 31 by tightening a set screw 35 to be screwed into 32, 33.

  The cleaner connection base 32 is formed with a nipple connection hole 36 communicating with the inside of the can 30 and a large-diameter hole 45 having a large capacity at the lower portion of the nipple connection hole 36. The nipple connection hole 36 has a stepped hole with a large diameter at the top, and the tip of the nipple 8 of the vacuum cleaner A can be inserted into and removed from the large diameter hole at the top. Further, a packing 38 is supported on a step portion 37 formed on the inner periphery, and the packing 38 is brought into close contact with the tip of the nipple 8 in a state in which the nipple 8 is inserted so as to maintain airtightness.

  Instead of the packing 38, a ring groove is formed on the inner periphery of the nipple connection hole 36, and an O-ring is attached to the ring groove so as to maintain airtightness between the connection portion of the nipple connection hole 36 and the nipple 8. It may be.

  On the other hand, the hose connection base 33 is formed with an inclined hose connection hole 39 that faces obliquely downward, and the suction hose 40 can be connected to the hose connection hole 39.

  The suction recovery device shown in the embodiment has the above-described structure. When recovering a small amount of collection object such as dust, the vacuum cleaner A is extracted from the cleaner connection base 32 and compressed air such as an air compressor (not shown) is shown. An air supply hose H connects the supply source and the air inlet of the air supply path 16 provided in the handle 2 of the vacuum cleaner A.

  When the lever 17a is grasped and the on-off valve 17 is opened in the connected state to the compressed air supply source, the compressed air is injected from the air injection nozzle 11 into the diffuser pipe 1 and accelerated to flow out from the air outlet 6, and the compressed air A suction force is applied to the nipple 8 by the ejector action.

  For this reason, by connecting the suction nozzle 9 shown in FIG. 10 to the nipple 8, the collection object such as dust can be sucked by the suction nozzle 9. The sucked collection object is transported from the diffuser pipe 1 into the dust bag 12 and collected by the dust bag 12.

  As described above, when the on-off valve 17 is opened, a suction force is applied in the nipple 8, and therefore, as shown in FIGS. 1 and 2, with the lid 31 attached to the can body 30 of the recovery container B, The inside of the collection container B can be decompressed by inserting the tip of the nipple 8 into the nipple connection hole 36 formed in the cleaner connection base 32.

  At this time, since a pulling force is applied to the nipple 8 toward the inside of the collection container B, the tip of the nipple 8 comes into close contact with the packing 38 to ensure sealing performance, and the collection container is secured. The inside of B is effectively decompressed.

  Therefore, if the suction hose 40 is connected to the hose connection hole 39 formed in the hose connection base 33, a suction force is applied to the suction hose 40, and the suction hose 40 causes dust or the like to be collected. The collection object can be aspirated.

  The sucked collection target object swirls in from the top of the collection container B, descends while swirling, and accumulates on the bottom, and the collection object B can be collected by the collection container B. At this time, an upward airflow is generated in the central portion of the collection container B, and if fine dust is mixed in the collection object collected by suction, the dust rides on the upward airflow. There is a possibility that the gas flows from the nipple 8 into the diffuser pipe 1 and flows out from the air outlet 6.

  At this time, since the dust bag 12 is connected to the air outlet 6, the dust is prevented from being captured by the dust bag 12 and flowing out to the outside, and the external environment is not deteriorated.

  In the use of collecting the collection object in the collection container B as described above, the engagement hook 18 is engaged with the end of the lever 17a as shown in FIG. 2, or as shown in FIG. The engaging ring 19 is set in a state of straddling the outer periphery of the grip portion 13 and the lever 17a, and the lever 17a is held open.

  As described above, in the suction recovery apparatus according to the embodiment, there are two types of use, that is, the use of collecting the collection object in the dust bag 12 and the use of collecting the collection object such as dust in the collection container B such as a pail can. Can be used, and the usage state can be changed according to the type and amount of the object to be collected, which is extremely convenient.

  It should be noted that when the collection object is sucked and collected using the collection container B such as a pail can, the collection object may be a liquid such as a factory waste liquid.

  In FIG. 3, the cleaner connection base 32 and the hose connection base 33 are separately attached to the lid 31 of the recovery container B. However, as shown in FIG. 7, the cleaner connection base 32 and the hose connection base 33 are provided. May be common. By using the pedestals 32 and 33 in common, the attachment can be facilitated as compared with the case where the respective pedestals are individually attached to the lid.

  Here, as shown in FIGS. 3 and 5, a U-shaped handbag 41 is connected to the cleaner connecting base 32 so as to be raised or lowered, or a groove is formed on the outer periphery of the cleaner connecting base 32 as shown in FIG. When the fingertip engaging recess 42 made of is formed, the lid 31 can be easily attached and detached.

  FIG. 9 shows another embodiment of the suction recovery apparatus according to the present invention. This embodiment is different from the suction recovery apparatus shown in FIGS. 1 and 2 in that the filter case 50 is assembled between the cleaner connection base 32 and the nipple 8 of the vacuum cleaner A.

  Here, the filter case 50 has a connecting tube 51 that can be inserted into and removed from the nipple connecting hole 36 of the cleaner connecting base 32 at one end, and a nipple connecting hole 52 through which the nipple 8 of the vacuum cleaner A can be inserted and removed. The filter 53 is built in.

  As described above, by incorporating the filter case 50 between the cleaner connecting base 32 and the nipple 8 of the vacuum cleaner A, fine dust rising on the rising air current in the collection container B is primarily captured by the filter 53. In addition, since it can be secondarily captured by the dust bag 12, leakage of dust to the outside can be almost certainly prevented.

  In addition, as shown in FIG. 2, you may make it capture | acquire primary fine dust by incorporating the filter 53 in the large diameter hole part 45 formed in the base 32 for cleaner connection.
